124" build...I'll let the cat out of the bag

[No Cents]

I just went back to S&S's web site...looking at their new 3 piece flywheels because I thought I read at the bottom that they have what is called "special order"...which I'm taking it as flywheels custom made to your spec's.
It states to call them on the web site.

My motor is a evo merch 131

here is a picture of a set of S&S 4 3/8 bore pistons

Did you notice wrist pin location in oil ring groove?
John

Stroker pistons have been doing that for years.  A 8 inch rod can cause some problems with TDC dwell and best rod to crank angle.  More need to be thought about besides just raising a back bone.  That's pretty easy compared to what else need to be thinked about and planed.

I do realize 8 in rods will require new rods,barrels,piston,intake manifold,pushrods,tubes,and I will have to fabricate or modify my exhaust pipe

I was just mentioning it.

Several things can cause piston scuffing. I've taken apart some really good running engines that had scuffed pistons. If the leak-down is acceptable and she runs good, I say let 'er buck.

Wonder if I have room for .250" to squeeze a 139" and a bit more compression and head work.

Hi
I'm thinking same thing ran real good no loss in compression,consumes no oil.Piston maybe a little heavier above wrist pin,skirts aren't very long and ring pack has been lower 115 thousand.

Speaking about going bigger, Is anyone out there running a  145"?   

We are working on the bigger CI  ( two engines at this time ) with the new T2 cases. But at this moment there are some parts that are not ready yet. So looks to be first of the year to see the rest of the parts in production per say.

Steve,

How many sets of the cases do you have?  Rumor had they will support a 139 or 145 any validity to that?  Will we be able to go larger than 70 mm the Jim's gave me a fit with the HPI 62/62

[HD/Wrench]

unbalanced,.. feel free to contact us directly on the T2 cases & builds  thank you.

[Unbalanced]

Steve I am really tied up with work heading cross country could you post a picture of the cases specifically the bore area and pistons squirters.


I will follow up with you after that when I get back early next week.

Thanks Buddy

Time to sell that 124 Ray and run with the big dogs 135!!!!!!!!!!!!!!!

If I want to race it on the strip eventually in the bagger class...I have stay a 124.

Ray, they do allow overbore to 127"

[Hollywood]

  Bigger is always better Ray. I will reveal my build this spring   

[No Cents]

 
Thanks...I knew that Darren. I don't plan on going to that big of an over bore on the 1st time it needs a little freshening up. I'd hope to get a year or so out of this engine before it needs any boring done.
Hollywood...I do have plans of building another engine someday...I promise it will be a little bigger than a 124"er

Something to shoot for Ray.

nothing like that...just something out of the T2 cases will be fine for my final engine build. I'm thinking of going with a big bore low compression cross country cruiser.

I thought 11.2 was low compression

By then you'll be looking for a shark nose. Jim might not let it on his drums.

Yeah he will, I broke him of that a couple years ago, I think he's beginning to actually like a Road glide, but he'd never admit it in front of his batty friends..

  mines at 11.10:1...and I think it's definitely not high

My point exactly, I thought you were kidding, and actually talking about adding those pistons you have...my bad.

Carry on.

[No Cents]

those pistons will set it at 11.86:1.
I'll definitely have to run the CR650 cams or the S&S 640's when I do the compression bump to keep the ccp's down around the 205 area.
